| public static com.sun.mail.imap.protocol.MessageSet[] | toMessageSet(Message[] msgs, com.sun.mail.imap.Utility$Condition cond)Run thru the given array of messages, apply the given
Condition on each message and generate sets of contiguous
sequence-numbers for the successful messages. If a message
in the given array is found to be expunged, it is ignored.
ASSERT: Since this method uses and returns message sequence
numbers, you should use this method only when holding the
messageCacheLock.

continue;

// Apply the condition. If it fails, skip it.

continue;
MessageSet set = new MessageSet();

// the outer loop, so decrement 'i' to cancel the
// outer loop's autoincrement

| | public static com.sun.mail.imap.protocol.UIDSet[] | toUIDSet(Message[] msgs)Return UIDSets for the messages. Note that the UIDs
must have already been fetched for the messages.
